I have the same problem all the others have. Suddenly (12 hours ago), my phone started fully shutting down whenever screen lock was activated. (Related or not, I have been using the fingerprint sensor a lot recently for activation, rather than face recognition or PIN)..
Restarts, soft-resets, cache deletions, app updates, recent app deletions, etc. do NOT solve the problem.
Keeping the phone on at all times does solve the problem
Turning off the fingerprint sensor screen unlock (as advised by others on this site) does solve the problem. One can still use the fingerprint sensor for apps, just not for unlock.
Presumably this is a Samsung software update problem?
Suppose it is possible that this is some combination of phone going bad AND software problem.
But it is useful to have fingerprint sensor unlock operational.
Is there any software patch/update/fix for this from Samsung?
Or does it mean that a number of users phones are going bad in the exact same way ?
